KVM qemu-kvm "ext4_fill_flex_info()" Denial of Service Vulnerability

Hi all.

Yesterday, secunia has released an advisory about qemu-kvm.
https://secunia.com/advisories/48645/

This seems to describe and 'old' kernel bug, but I don't know if there is a 'link' between the ext4 issue and kvm.

Can you explain a bit this issue?

Thanks in advance.

Appears to be 100% unrelated to kvm.
